Translation error/Agent failure

Hello G’s! So I’ve built this Lead Capture chatbot for a client and the client wants the Chatbot’s language to be Mongolian. I’ve tried giving the Agents inside of Voiceflow a prompt to always answer in Mongolian and to use Gemini. But I’m facing this problem where whenever the Voiceflow build triggers and tries to respond with Mongolian amd use Gemini, it crashes.

It crashes with not only Gemini, but every other LLM bigger and comprehensive.

Can you guys recommend ways to somehow Translate those messages? If you guys could know how to translate the output, please recommend the way. Thank you! This is urgent
